OIL-WELL DEVICE. J

Patented Dec. 5, 1905.

Application med my S, 1905. serai No. 268.220.

- Vania, have invented certain new and useful Improvements in Oil-WellDevices, of which the following is aspecification, reference behadtherein to the accompanying drawings. ,l This invention relates tocertain new and useful improvements in working barrels for oil-wells;and the invention has for its object the provision of novel means inconnection with a working barrel for agitating the sand formation of anoil-well to increase the flow of the well and its general production.

In connection with the agitating `means of my improved working barrel Iemploy'novel means for regulating the agitation andfor producing anagitation at any desired pointV within the sandforrnation of the well. v

With the above and other objects in view the inventionv finally consistsin the novel construction, combination, and arrangement of parts, whichwill be hereinafter more fully described and then specifically pointedout in the claims, and referring to the drawings tional view of one ofthe plugs used inconaccompanying this application like numerals ofreference designate corresponding parts throughout the severalviews, inwhich- Figure 1 is a vertical sectional view of a working barrelconstructed in accordance with my. invention, illustrating the samepositioned Fig. 3 is a cross-sectional view taken on the l line w w ofFig. 1.

In the accompanying drawings, Ihave illus- 7 of the drawings.

tratedthe lower end of a pipe 1, which is adapted to extend into thesand formation 2 of an oil-well, and upon thev end of this pipe it hasbeen the practice to'secure the ordinary type of working barrel, whichis generally used in oil-well pumping. I dispense with the ordinary typeof workingbarrel and employ a specially-constructed barrel adapted toagitate the sand'formation 2. In order to support my improved barrel, Iprovide the nlower end of the pipe l with a sleeve 3, having a centraldepending pipe 4, the upper end `of which terminates in an `open1ng 5,formed in the sleeve 3. The lower end of the pipe 4 is provided with aplurality of circumferentiallyarranged openings 6. ,The sleeve .3 isprovided with a depending interiorly-screw-threaded flange 7 and in thisiange is secured the .screw-threaded end 8 of my improved workingbarrel. The working barrel consists of an inner annular shell 9'and anIntegral outer `shell 10, these shells providing an annular compartment1l Within the working barrel. The shells are braced byvertically-disposed ribs 11a, and the annular compartment 11 iscentrally partitioned by a horizontal wall 11b.

some of the openings 12L of the sleeve 12.'

To retain the sleeve 12 within the lower end of the barrel, I employ acollar 15, (see Fig. 12,) this. collar being secured upon thescrewthreaded end 16 of the barrel.

Both ends of the shell 10 are provided with openings 16 and 17, and inthe opening 17 is mounted a screw-threaded plug 18, whilein the opening16a is secured an upwardly-extending. tubeA 19, which `carries a sleeve20. -This sleeve is clearly illustrated in Figs. 6 and The one end ofthe sleeve IOO is screw-threaded, as indicated lat 21, kto supportanother section of tubing 22 .in case it is desired to use the same. Inthe sleeve 2O upon with a radiallydisposed aperture 24, whichestablishes communication between the tubing 19 and the exterior of thesleeve.

The outer shell 10 is provided with a plurality of staggeredly-arrangedscrew-th readed apertures 25, and in each one of these aper- 'turesIsecure a plug 26, which is clearly illustrated in Figs. 4 and 5 of thedrawings. Each plug is provided with an annular groove 27, forming acollar 28, which is provided with a plurality of vertically-disposedapertures 29. rIhe plug is provided with an opening 30, communicatingwith the annular groove 27 by a port 31. These plugs are screw-threaded,as indicated at 32, whereby they may be secured in the screw-threadedopenings 25 of the outer shell 10.

In operation the oil passing through the working barrel is adapted topass through the openings 6 of the pipe-4, openings 14a of the innershell 9 into the annular compartment 11 of the working barrel, fromwhere it passes through the plugs 26, mounted in the openings of theouter shell 10. This oil is adapted to spray and contact with the sandformation of the oil-well and agitate the same, whereby a larger flow ofthe well will be produced. At times it may be necessary to agitateportions of the same formation which cannot be conveniently reached bythe working barrel, and for this reason I have devised the tubing 19 andthe sleeve 20, which is adapted to carry the oil upwardly and distributeit against the sand formation above the working barrel.

The plugs 26 which I employ are specially constructed to prevent theplug from rusting or corroding, and in some instances I may find itadvisable to dispense with the small openings 29 of the plugs andcontinue the openings 30 right through the plug-body. In some oil-wellsand formation greater agitation is required in connection with somethan with others, and should it be desired to decrease the agitation anumber of plugs 26 can be removed and the ordinary type of plug 37secured in the openings 25, consequently reducing the amount of oilejected through the outer shell 10.

In connection with the working barrel I may employ a gravity-valve 36,which is preferably mounted in the sleeve 15, this valve being employed'to prevent the oil passing downwardly into the Well, but permitting ofthe same passing upwardly. It will be observed that l have provided theupper end of the Working barrel with the depending pipe 4, which issubstantially the same as the detachable sleeve 12, with the exceptionthat the sleeve 12 can be readily removed and a sleeve 38 placed thereinto close the openings 14a of the working barrel in case it is notdesired to use the same. In some instances it may be desirable to use adetachable sleeve in lieu of the pipe 4, in which case a collar 39 (seeFig. 10) is used in lieu of the collar 3.

It will be observed by the construction of my improved working barrelthat either the pipe 4 and the sleeve 12 may be used at one time oreither end of the working barrel used independently of the other end,and I do not care to confine myself to the manner in which it is used,as the working barrel can be readily reversed, the plug 13 being removedand replaced by the pipe 19, while the opening 16 is closed by the plug18, it always being essential that the valve 36 be used at the bottom ofthe working barrel.

I have provided the openings 6 at the lower end of the pipe 4 in orderto cleanse the oil passing into the annular compartment l1 of allsediment or foreign ingredients detrimental to the sand formation 2, theperforated plate 23 of the sleeve 2O being employed for the samepurpose.

It is thought from the foregoing that the construction, operation, andadvantages of the herein-described working barrel will be apparentwithout further description, and various changes in the form,proportion, and minor details of construction may be resorted to withoutdeparting from the spirit of the invention or sacrificing any of theadvantages thereof.
